Abstract

The utility model relates to a mould for pressing and wrapping wood chips with sawdust to make the wood chips joint tightly, which comprises a convex mould, a concave mould, and a middle mould supported by a bracket on a groove, wherein, a gap for wood chips to be inserted in is arranged between the middle mould supported by the bracket and the groove, and the mould can be used for pressing and wrapping wood chips with sawdust to form wood boards which are covered with the outer peel of the wood chips. The shapes of finished products do not need cutting with the utility model. The redundant parts of the wood chips can be ablated while compressing. Thus, the utility model can ensure uniform and stable quality and strength of semi-finished products which are wrapped with wood chips, and save processing time of cutting the wood chips.

Description

Wood chip can be pressed and wrap up in the mould that wood chip makes its fluid-tight engagement

The relevant a kind of mould of the utility model refers to that especially a kind of wood chip can the pressure wrap up in the mould that wood chip makes its fluid-tight engagement.

Usually timber processing back produces a lot of wood chips, not only handles inconvenience, and easier contaminated environment causes public hazards.

Traditional semi-finished product made from wood dust are that levels is binded veneer, and the outer rim in middle level still can find out it is the processed goods of wood chip at a glance, and, because the middle level wood chip is organized not as above, lower floor's veneer is closely with integrated, make these processed goods cause bad order easily, moth and intensity are not good easily, and density is loose, humidity not, shortcoming such as be full of cracks easily.

Make the plank semi-finished product of above-mentioned traditional wood dust moulding, the mould that is subjected to pressurize vertically limits, cause the semi-finished product of this kind wood dust moulding to manifest the wood chip tissue in middle level, and need be coated on the wood chip tissue that is exposed outside with filler (clay, two degree priming paint) simultaneously, processed complex, and make half-finished use value lower, and this problem still can't effectively be improved so far.

Main purpose of the present utility model provides a kind of wood chip can the pressure and wraps up in the mould that wood chip makes its fluid-tight engagement, it is above rectilinear pressuring method down, can once the wood chip pressure be wrapped up in wood chip and make it closely be coated on the upper and lower and middle level outer rim of semi-finished product, make semi-finished product plank appearance all coat veneer.

Another purpose of the present utility model provides a kind of wood chip can the pressure and wraps up in the mould that wood chip makes its fluid-tight engagement, its upper and lower layer when extrusion forming all can directly add thin this film, needn't cut finished form, can in pressurization, the unnecessary part of veneer neatly be excised, make quality, the intensity of semi-finished product outsourcing veneer unified stable, and can save the machining period of wood chip cutting.

The technical solution of the utility model is: a kind of wood chip can the pressure wrapped up in the mould that wood chip makes its fluid-tight engagement; include a punch (patrix or movable mold); one die (bed die or fixed die) and on die, constituting by mould in the hollow shaped as frame of support support; in the shaped as frame supported of fast support between mould and the die, have the gap that can insert for veneer.Mould is pressed to wrap up in and is made the wood chip extrusion modling coat the semi-finished product of wood chip for full surface whereby.

The utility model can be with the wood chip regeneration, and the change refuse is a good timber, except can handling wood chip in a large number, and can increase the value of wood chip, increases economic efficiency, and has the innovation practicality.

Now reaching preferred embodiment in conjunction with the accompanying drawings is elaborated as follows to the utility model:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an operation chart of the present utility model.

Fig. 3 is an enforcement action schematic diagram of the present utility model.

As Fig. 1, Fig. 2, shown in Figure 3; of the present utility model wood chip can the pressure wrapped up in the mould that wood chip makes its fluid-tight engagement; include: a punch 11 (or deserving to be called mould or movable mold); one die 12 (or claiming bed die, fixed die) and one is located on the die, is made of mould 14 in the hollow shaped as frame of support 13 supports.

Punch 11 can be borrowed impressed pressure and with the action of vertical depression, the hollow inside of mould 14 in being forced to; Should between mould 14 and the bed die 12, by this support support and maintain a suitable gap 15, this gap 15 can be inserted for a veneer 16 and is blocked between middle mould 14 and the bed die 12.

During actual pressurized operation, earlier veneer 16 15 is inserted from the gap, the quantitative wood chip 18 that will be mixed with glutinous agent is again poured the inside of middle mould 14 hollows into, simultaneously cover another veneer 17 on middle mould upper strata, the starting pressure source, make patrix 11 vertically downward from the top, with this upper strata veneer 17, wood chip 18 and lower floor's veneer 16 are squeezed to bed die 12 inner moulding, a series of actions whereby simultaneously, make the semi-finished product outer rim of moulding coat veneer fully, and in extruding simultaneously, integrate with middle mould 14 and bed die 12 threes, make wood chip 18 become and the identical shape of bed die 12 die cavitys by patrix 11, and all coat veneer, and unnecessary veneer will excise naturally.

It should be noted that the veneer 16 of inserting gap 15, its area should be greater than the bottom surface and the lateral margin face area sum of molding semi product, and the area of upper strata veneer 17, should be greater than the top area of molding semi product.Again, punch 11 and middle mould 14 in the mould all have the outer edge surface of slightly inclined, and can become the structure of tight fit when pressings.

Therefore, of the present utility model wood chip can the pressure wrapped up in the mould that wood chip makes its fluid-tight engagement, can make the wood chip extruding coat the semi-finished product of wood chip for full surface through above-mentioned action, cut edge simultaneously, moulding (can be engraved on, bed die in) according to required form, everybody can operate, and does not need the technical staff to cut timber and numerous and diverse processing, more can save great amount of cost and log material, real is a kind of innovation, progress and economic, practical timber processing mold.

Claims

1, a kind of wood chip can the pressure wrapped up in the mould that wood chip makes its fluid-tight engagement, it is characterized in that: be by a punch, a die and on die, constitute by mould in the hollow shaped as frame of support support, between mould and the die, be provided with a gap that can supply veneer to insert in the shaped as frame that described support is supported.

2, according to claim 1 wood chip can the pressure wrapped up in the mould that wood chip makes its fluid-tight engagement, and it is characterized in that: described punch and middle mould are equipped with the outer edge surface of slightly inclined, and can become the structure of tight fit when the moulding of pressing wood chip.
